FIELD OF THE INVENTION

The present invention relates to packaging systems for packaging products, typically poultry products, using clips.

BACKGROUND OF THE INVENTION

Known whole bird poultry packaging systems include those described in U.S. Pat. No. 5,782,056 to May et al.

SUMMARY OF EMBODIMENTS OF THE INVENTION

Embodiments of the invention are directed to automated meat, typically poultry (e.g., whole-bird), packaging systems. The packaging systems include a plurality of spaced apart holding stations that are spaced apart about a defined endless travel path (typically a substantially circular path) and cooperate with a plurality of spaced apart cooperating workstations positioned along the travel path to automatically package the product (e.g., bagged poultry). The workstations and/or the holding stations travel about the endless path to package the poultry. In some embodiments, the holding stations travel substantially in concert about the travel path to serially communicate with the workstations.

The plurality of stations can be between about 4-12 stations (typically 5 or 8) that travel in concert about the travel path and can be held by a platform with at least one, typically a central, upstanding column. The travel path can be substantially circular such that the holding stations rotate about a substantially circular travel path about the centerline of the column.

At least some, typically all, of the workstations can reside proximate an outer perimeter of the travel path and extend mechanisms that contact the product holder and/or bags thereon to carry out defined operations. The workstations may include a poultry loading station, a hocking station, a clipper station and a bag loading station. The packaging system can include a drive system that can cause the product (e.g., poultry) holders to travel downward a distance between the hocking and clipper workstations, remain at that level through the bag loading workstation, then automatically rise between the bag loading workstation and the poultry loading workstation.

Embodiments of the invention are directed to automated (poultry) bagging packaging systems that include a platform and a plurality of spaced apart poultry holding stations mounted to the platform. At least one of the platform or the poultry holding stations rotates about a defined endless travel path to automatically serially position a respective holding station to be in communication with each of a plurality of different workstations.

Other embodiments are directed to methods of packaging whole bird (meat objects) that include: (a) placing a whole bird into an open bag; (b) automatically rotating the bird in the open bag to a first hocking workstation; (c) automatically hocking the bird in the open bag; (d) automatically clamping the hocked bird to retain the legs in a desired orientation; (e) automatically rotating the hocked bird in the open bag to a second clipping workstation while translating the hocked, clamped bird a distance downward; and (f) automatically applying at least one clip to a gathered end portion of the bag with the hocked bird in the bag.

The placing step can be carried out automatically by mechanically transferring a respective whole bird from a suspended shackle aligned with an open bag held by a poultry holder under the aligned suspended shackle. The method can be carried out using a frame holding a plurality of circumferentially spaced apart poultry holders that rotate through a circular travel path that places a respective poultry holder in communication with the hocking workstation, then the clipper workstation.

The method may include stopping the whole bird in the package for a defined time at the first hocking workstation before rotating the hocked bird in the bag to the second clipping workstation, and stopping the hocked whole bird in the package at the clipping workstation for the same defined time before rotating a respective clipped package to a discharge location.

Yet other embodiments are directed to methods of packaging poultry that include: (a) providing a plurality of spaced apart poultry holders that travel about a closed loop travel path; (b) translating the poultry holders in concert so that each respective poultry holder automatically serially travels through a plurality of defined spaced apart workstations residing proximate a perimeter of the travel path, including a loading workstation and a clipping workstation; then (c) successively automatically providing a packaged whole bird in a clipped bag in response to the translating step.

The methods may include, at the clipping workstation, automatically applying at least one clip to a gathered tail portion of a bag holding poultry therein at the clipping workstation, automatically cutting a tail end off the clipped bag at the clipping workstation and automatically collecting the cut tail end for disposal.

Yet other embodiments are directed to automated product bagging systems that include: (a) a plurality of spaced apart product holder stations that travel in concert about a defined continuous travel path; and (b) a plurality of spaced apart automated workstations positioned along the travel path that cooperate with the product holder stations to automatically package the product. One of the automated workstations is a clipping workstation that applies at least one clip to a gathered tail portion of a covering holding a respective product.

The plurality of stations is typically between about 4-12 stations.

The bagging system may also include a mounting platform with a central upstanding column that holds each of the product holder stations. The travel path can be substantially circular such that the product holders rotate about an axially extending centerline of the column.

The bagging system product holder stations can be whole-bird holder stations and the workstations all reside proximate an outer perimeter of the travel path.

The bagging system can also include a drive system that is configured to (a) translate the product holders downward a distance of between about 6-18 inches to reside at a lower level between hocking and clipper workstations relative to a workstation upstream thereof, (b) maintain the product holders at the lower level through a bag loading workstation, then (c) automatically raise the product holders upward a distance to a product loading level between the bag loading workstation and the poultry loading workstation.

Still other embodiments are directed to a computer program product for operating a poultry bagging system with a plurality of poultry holding stations that rotate in concert about a continuous travel path that moves the product holding stations through a progression of spaced apart different workstations. The computer program product includes a computer readable storage medium having computer readable program code embodied in the medium. The computer-readable program code includes: (a) computer readable program code configured to control a travel speed of the poultry holding stations along the travel path; (b) computer readable program code configured to direct the holding stations to rotate and stop in concert so that each holding station is held for a defined time at the different workstations along the travel path; (c) computer readable program code configured to direct to the holding stations to automatically travel a distance downward as they are traveling along the travel path so that one or more holding stations are at a different vertical level relative to others at one or more positions along the travel path; and (d) computer readable program code configured to monitor sensors that determine a position of one or more of the holding stations relative to one or more workstations and directs at least one workstation to carryout defined operations when a holding station is in position thereat.

Yet other embodiments are directed to packaging systems that include: (a) a plurality of holding stations that rotate in concert about a continuous travel path whereby the product holding stations move through a progression of spaced apart different workstations; (b) a plurality of spaced apart workstations positioned along a perimeter of the travel path, at least one of the workstations being a clipping workstation with a clipper that automatically applies at least one clip to a product held in a covering by one of the holding stations; and (c) a controller configured to (i) control a travel speed of the holding stations along the travel path, (ii) direct the holding stations to rotate in concert, then stop in concert so that each holding station is held for a defined time at the different workstations along the travel path, (iii) direct at least a portion of the holding stations to automatically travel a distance downward as they are traveling along the travel path so that one or more holding stations have a portion that is at a different vertical level relative to others at one or more positions along the travel path, and (iv) monitor sensors that determine a position of one or more of the holding stations relative to one or more workstations and direct the workstations to carry out defined operations when a holding station is in position thereat.

Although described above with respect to method aspects of embodiments of the present invention, it will be understood that these features may also be embodied as systems, sub-systems, modules and/or computer program products.

It is noted that aspects of the invention described with respect to one embodiment, may be incorporated in a different embodiment although not specifically described relative thereto. That is, all embodiments and/or features of any embodiment can be combined in any way and/or combination. Applicant reserves the right to change any originally filed claim or file any new claim accordingly, including the right to be able to amend any originally filed claim to depend from and/or incorporate any feature of any other claim although not originally claimed in that manner. These and other objects and/or aspects of the present invention are explained in detail in the specification set forth below.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The present invention will now be described more fully hereinafter with reference to the accompanying figures, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like numbers refer to like elements throughout. Features described with respect to one embodiment may be used alone or with another embodiment although not specifically described with respect to that other embodiment.

In the figures, certain layers, components or features may be exaggerated for clarity, and broken lines illustrate optional features or operations unless specified otherwise. In addition, the sequence of operations (or steps) is not limited to the order presented in the claims unless specifically indicated otherwise. Where used, the terms “attached”, “connected”, “contacting”, “coupling” and the like, can mean either directly or indirectly, unless stated otherwise. The term “concurrently” means that the operations are carried out substantially simultaneously.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The term “frame” means a structure used to support one or more assemblies, modules and/or components. The frame can be floor mounted (fixed or moveable) or a wall and/or ceiling supported frame.

The term “automated” means that operations can be carried out substantially without manual assistance, typically using programmatically directed control systems and electrical and/or mechanical devices. The term “semi-automatic” means that operator input or assistance may be used but that most operations are carried out automatically using electromechanical devices and programmatically directed control systems. The term “workstation” refers to a particular machine assembly at a location that is configured to carry out a defined operation or operations or otherwise perform a certain function, e.g., “work” that is associated with packaging a product, e.g., a clipping workstation is defined to be programmatically controlled to automatically (electromechanically) apply at least one clip to a casing or covering such as to a gathered end portion of a flexible bag. Consumable items used by one or more workstations may be replaceable by an operator.

In the description of embodiments of the present invention that follows, certain terms are employed to refer to the positional relationship of certain structures relative to other structures. As used herein, the term “front” or “forward” and derivatives thereof refer to the general or primary direction that the product travels along a defined travel path to form a packaged product; this term is intended to be synonymous with the term “downstream,” which is often used in manufacturing or material flow environments to indicate that certain material traveling or being acted upon is farther along in that process than other material. Conversely, the terms “rearward” and “upstream” and derivatives thereof refer to the directions opposite, respectively, the forward and downstream directions.

Embodiments of the present invention can be used for packaging any suitable object or objects using a clipper to apply clips to seal products held in flexible bags. The flexible bags can comprise any suitable material or combinations of materials (edible or inedible, natural or synthetic) such as, but not limited to, one or more of collagen, cellulose, elastomeric, polymeric and/or plastic casing, and netting. When used with food products, the flexible bag should be food-compatible. The objects for packaging can be solid or semi-solid objects, flowable product such as seed, granules or powder (edible or inedible), and the like, typically food objects. Embodiments of the invention are particularly useful for packaging “whole bird” food products, which as known to those of skill in the art may be interchangeably be referred to as “poultry”. Embodiments of the invention may be particularly suitable for packaging whole-bird or poultry in wicked bags. In some embodiments, the poultry may have a weight of between about 2-12 lbs, typically between about 4-6 lbs, and more typically between about 4-5.5 lbs, on average. However, other size and weights may be accommodated.

The terms “continuous” and “endless” refer to a travel path with a closed perimeter, e.g., a closed loop. The continuous or endless travel path can be substantially circular, but may also have other shapes such as oval, polygonal and the like.

Referring now to the figures, <figref idref="DRAWINGS">FIGS. 1-4</figref> illustrate an example of an automated packaging system <b>10</b>. As shown, the system <b>10</b> includes a support frame/platform <b>11</b> and a plurality of spaced apart (poultry) holding stations <b>14</b> mounted to the platform <b>11</b>. The holding stations are identified as <b>14</b>₁-<b>14</b>₈but lesser or greater numbers of the holding stations <b>14</b> may be used. The holding stations <b>14</b> are typically equally spaced apart and travel in concert about an endless or continuous travel path <b>10</b><i>p. </i>

In operation, the holding stations <b>14</b> can travel (e.g., rotate) about the defined endless travel path <b>10</b><i>p </i>to automatically serially position a respective holding station <b>14</b> to be in communication with each of a plurality of different workstations, shown as five different spaced apart workstations labeled as stations “<b>1</b>”-“<b>5</b>” in an exemplary order in <figref idref="DRAWINGS">FIG. 1</figref> and also identified by reference numbers, <b>15</b><i>w</i>, <b>20</b><i>w</i>, <b>25</b><i>w</i>, <b>30</b><i>w </i>and <b>35</b><i>w</i>. However, additional or lesser numbers of workstations may be used and different workstations for different operations may also be used. In addition, the different workstations can be combined into a combination workstation that performs the operations of the separate workstations. The workstations can be configured to automatically carry out defined operations associated with packaging to reduce operator labor. The holding stations <b>14</b> can rotate or travel in either direction, e.g., clockwise or counterclockwise, shown as counterclockwise in <figref idref="DRAWINGS">FIG. 1</figref>, but the direction of rotation may dictate the placement of the workstations so that the desired work progression is serially provided (in the desired order).

Typically, the system <b>10</b> is substantially automated and does not require a dedicated operator. A “floating” operator can be used to oversee or monitor a single system or several of these systems <b>10</b> (<figref idref="DRAWINGS">FIG. 11</figref>). If a “jam”, misfeed or other operational error occurs, the system <b>10</b> can generate an alarm and/or cease operations (and rotation of the stations as appropriate). Typically, an operator will only be needed to load bag material (e.g., sets of pre-wicked bags) at the bag loading station <b>35</b><i>w </i>(where used) and reload clips at the clipping station <b>25</b><i>w. </i>

The first workstation <b>15</b><i>w </i>can be a loading/dropping station which receives the object/objects (e.g., whole bird) for packaging. For example, poultry <b>101</b> (<figref idref="DRAWINGS">FIG. 3</figref>) can be transported by a moving (overhead) shackle or in-line or overhead conveyor <b>100</b> (such as conventional overhead shackle systems) and placed into an open bag <b>40</b> (<figref idref="DRAWINGS">FIGS. 2-4</figref>) held by a respective holder <b>14</b> at this workstation <b>15</b><i>w </i>with the open end of the bag facing upward. The holding station placement can be automatic by synchronizing the movement of the holding stations <b>14</b> to that of the input feed system <b>100</b>. For example, the holders <b>14</b> can be configured to move a defined distance, then stop at a workstation or resting location for a defined time, then move again a defined distance to stop at the next workstation, etc. (e.g., a “stop” and “go” operation). When stopped at the first workstation <b>15</b><i>w</i>, the holder <b>14</b> can be aligned under a shackle so that when released, the bird drops into the bag <b>40</b> held by the holder. A mechanical arm (not shown) can also be used to facilitate the transfer of the bird from the input device to the bag held by the holder <b>14</b>. For an example of a mechanical grasper, see, U.S. Pat. No. 5,782,056, the contents of which are hereby incorporated by reference as if recited in full herein.

In other embodiments, a hopper <b>15</b><i>h </i>(<figref idref="DRAWINGS">FIGS. 10-15</figref>) can be aligned with the open bag at the input station <b>15</b><i>w </i>(station “<b>1</b>”) to input material (whole bird, powder, gel, fluid, granules or other objects).

The second (indexed) position or workstation <b>2</b> can be a hocking (and pushing) workstation <b>20</b><i>w</i>. The operations can be performed while the bird is oriented or held substantially vertical in the bag <b>40</b> by the holding station <b>14</b> with the legs closer to the open (top) end of the bag. A pushing/hocking procedure can be carried out on the legs of the bird. A “hocked” bird has the thighs of its legs held in close proximity to the sides of the carcass of the chickens. The pushing/hocking workstation <b>20</b><i>w </i>can include a hocking apparatus that can cooperate with the holding station <b>14</b> to hock the bird in the (wicked) bag. Examples of hocking (pushing) devices are described in U.S. Pat. Nos. 5,782,056 and 7,178,310, the contents of which are hereby incorporated by reference as if recited in full herein. Further aspects of an exemplary hocking/pushing workstation <b>20</b><i>w </i>will be discussed below with respect to <figref idref="DRAWINGS">FIGS. 9 and 18A</figref>, <b>18</b>B, <b>19</b>A, <b>19</b>B, and <b>23</b>A-<b>23</b>D. Still further, in some embodiments, the system does not require a dedicated hocking station.

The third (indexed) position or workstation <b>25</b><i>w </i>can be a clipper workstation. At the clipper workstation with an automatic/semi-automatic clipper <b>25</b><i>c</i>, a bag tail can be automatically gathered and clipped by the clipper <b>25</b><i>c </i>while held in a generally or substantially upright position with the tail portion at the top. As conventional, the clipper at the clipping station can electronically operate to apply at least one clip, e.g., actuate, punch, and/or clip, and a knife can actuate/fire to cut a tail portion off the bag above the applied clip. The cut tail can be automatically captured and removed, e.g., using a vacuum take-away or other mechanism.

The fourth station and/or workstation “<b>4</b>” can be a discharge position/location and/or station <b>30</b><i>w </i>and can be in communication with a take-away conveyor, bucket or other receiver (not shown). This operation can be carried out “on the fly” while the holding station is moving downstream of the clipper to release the packaged object or as the station is halted while neighboring stations <b>14</b> reside at the clipper <b>25</b><i>w </i>and bagging workstations <b>35</b><i>w </i>and/or while one or more other neighboring stations <b>14</b> are at “rest” locations rather than active workstations. The discharge workstation <b>30</b><i>w </i>can be in communication with a conveyor, bucket or other receiver that automatically captures the packaged product when released from the holding station <b>14</b>. The discharge position or station <b>30</b><i>w </i>can be merely a “release” station or position. A pusher (not shown) or extendable arms mounted to the holding stations <b>14</b> can actuate to push or place the packaged product out of the bounds (or below or within an inner space) of the system <b>10</b> and onto or into a receiver that conveys or otherwise captures and provides the (clipped) packaged product so that the affected holding station <b>14</b> is now “empty” as it approaches the bag loading station <b>35</b><i>w. </i>

The fifth (indexed) position or workstation “<b>5</b>” can be bag loading station <b>35</b><i>w</i>. At this station a “new” bag can be loaded onto a respective holding station <b>14</b>. Further details of an exemplary bag machine are discussed with respect to <figref idref="DRAWINGS">FIGS. 5</figref>, <b>10</b>, and <b>16</b>A/<b>16</b>B below. The bag loading station <b>35</b><i>w </i>can load a respective bag onto an aligned holder station <b>14</b> (while moving or stopped). The bag loading workstation <b>35</b><i>w </i>can be reloaded with a bag supply (e.g., typically long lengths of attached bags) by an operator while the system is operating. The bag loader <b>35</b>L can have two bag-feed positions, one of which is active or operative at any one time. The bag loader <b>35</b>L can rotate about 180 degrees to allow for load side to be reloaded while the other is operative to dispense bags (<figref idref="DRAWINGS">FIG. 5</figref>). The product holding stations <b>14</b> can automatically “reset” to the starting orientation and position between stations <b>5</b> (<b>35</b><i>w</i>) and <b>1</b> (<b>15</b><i>w</i>) while translating along the travel path (and/or while at either workstation <b>35</b><i>w </i>or <b>15</b><i>w</i>).

In some embodiments, as a respective holding station <b>14</b> moves about that travel path <b>10</b><i>p</i>, typically between two adjacent workstations, such as between the hocking and clipper workstations <b>20</b><i>w</i>, <b>25</b><i>w</i>, at least a portion of the holding station <b>14</b> can lower or drop down a defined distance to reside at a lower level “L₂” as it approaches or resides in the next adjacent downstream workstation. For example, after a respective holding station stops for a defined time at the hocking workstation <b>20</b><i>w</i>, the holding stations <b>14</b> translate an indexed distance to place a respective holding station <b>14</b> downstream of the prior workstation, in line or queue for, or at, the next workstation <b>25</b><i>w</i>. While a respective holding station <b>14</b> with the hocked bird is translating between the hocking and clipping workstations, the base <b>24</b> (<figref idref="DRAWINGS">FIGS. 2-4</figref>) can travel downward a distance of between about 4 inches to about 2 feet, typically between about 10-12 inches. Other distances may be used or the workstation may hold the package at the same level throughout the travel path <b>10</b><i>p. </i>

Where used, the lowering operation can place the base <b>24</b> of the holding station <b>14</b> with the hocked bird at a lower level L₂at the clipping workstation <b>25</b><i>w </i>relative to the higher level L₁during loading and hocking (and bag reloading) (compare, for example, level one “L₁” with level two “L₂” in <figref idref="DRAWINGS">FIGS. 2 and 3</figref>). Similarly, after the discharge position or station <b>30</b><i>w</i>, the respective bases <b>24</b> of the holding stations <b>14</b> can travel back up to reside at the higher level L₁while the respective holding station <b>14</b> translates (e.g., rotates) between workstations <b>30</b><i>w </i>and <b>35</b><i>w</i>. Typically, the holding stations <b>14</b> reside at the higher level L₁at the (poultry) loading and hocking workstations <b>15</b><i>w</i>, <b>20</b><i>w</i>. Alternatively, the up and down translations can be performed at different workstations instead of between them. As shown, in <figref idref="DRAWINGS">FIG. 2</figref>, the clipper <b>25</b><i>c </i>at the clipping workstation is configured to apply a clip to an upper end portion of the bag <b>40</b> held on the lowered base <b>24</b> with the horn members <b>17</b> residing above the open end of the bag <b>40</b>.

<figref idref="DRAWINGS">FIGS. 5-7</figref> illustrate another exemplary embodiment of a packaging system <b>10</b>. In this embodiment, there are five (5) holding stations <b>14</b> and they are more closely spaced than the holding stations shown in <figref idref="DRAWINGS">FIG. 1</figref>. As shown, the travel path <b>10</b><i>p </i>is substantially circular. The only “blank” stop location or station is between the hocking/pushing station <b>20</b><i>w </i>(position <b>2</b>) and the clipper station <b>25</b><i>w </i>(position <b>4</b>). Thus, position “<b>3</b>” can be an inactive region or may be configured to be a “drop” zone where at least a portion of the holding station can travel down a defined distance in preparation for engaging the clipping workstation <b>25</b><i>w. </i>

All of the workstations <b>15</b><i>w</i>, <b>20</b><i>w</i>, <b>25</b><i>w</i>, <b>30</b><i>w</i>, <b>35</b><i>w </i>can be circumferentially spaced apart along the defined travel path <b>10</b><i>p </i>and at least some reside proximate but on the outside perimeter of the travel path <b>10</b><i>p</i>. Some neighboring workstations may be closer together than other neighboring workstations along the travel path <b>10</b><i>p</i>. In some embodiments, all the workstations can be equally spaced apart.

Referring to <figref idref="DRAWINGS">FIGS. 2-6</figref>, the floor-supported mounting frame or platform <b>11</b> can include a center post or column <b>12</b> and the travel path <b>10</b><i>p </i>can have a perimeter shape that (circumferentially) extends about a centerline <b>12</b><i>c </i>of the system <b>10</b>. The centerline <b>12</b><i>c </i>can extend upwardly through the post <b>12</b>. Thus, in some embodiments, the product holders <b>14</b> rotate in concert about the centerline <b>12</b><i>c</i>. The system <b>10</b> can be configured to operate using servo systems configured to provide control of position, velocity, and torque and monitor feedback of the motor(s). The valves and air supply can be fed through/from the center post <b>12</b> to each holding station <b>14</b>. The system <b>10</b> can be configured to be almost entirely automated without requiring manual assistance (other than potentially loading bags for the bag loading station) and can package about 10-50 birds/minute or even more, typically about 30 birds/minute, on average.

The system <b>10</b> can include a main drive system <b>50</b> that rotates the column <b>12</b> and stations <b>14</b> at the desired speed (and can vary the speed and stop and go increments depending on production requirements/inputs). The drive system <b>50</b> can comprise a servo to drive the column <b>12</b>. In some particular embodiments, the system <b>10</b> may optionally include a split main drive sprocket residing under the rotating column <b>12</b> surrounding the vertical column and a drive system in communication with the sprocket that rotates the rotating column at a desired speed. In some embodiments, the vertical support column <b>12</b> rotates in response to rotation of the sprocket, driven by gearboxes and servos as is known to those of skill in the art (allowing for the “indexed” or “start and stop” motion). The system <b>10</b> may also optionally include first and second vertically stacked and spaced apart plates, each of the plates being split into a plurality of adjacent pieces with a radially extending split line extending between the adjacent pieces. Where used, the stacked vertically spaced apart (support) plates can reside proximate the sprocket and may also be split plates to allow for ease of repair without requiring disassembly of the column <b>12</b> to remove the sprocket. The split line of the support plates can be aligned, as shown, or offset. The split line of the support plates may be offset with the split line of the sprocket or may be aligned (not shown). A suitable split sprocket is available from Martin Sprocket and Gears, Inc., located in Mansfield, Tex. See, co-pending, co-assigned, U.S. Patent Application Publication No. US-2009-0158688-A1 (e.g., <figref idref="DRAWINGS">FIG. 12</figref> therein), for further discussion of this drive configuration.

The system <b>10</b> can include air supply lines that connect to the pneumatic actuators <b>19</b>, <b>119</b> and clipper <b>25</b><i>c</i>. The holding station airlines <b>14</b><i>a </i>(<figref idref="DRAWINGS">FIG. 5</figref>) can travel down an outside perimeter and/or an internal channel of the column <b>12</b> to a pressurized air supply. The system <b>10</b> can include a single common main air supply that can be diverted to feed all of the actuators of the holding stations. Alternatively, each or groups of the actuators <b>19</b>, <b>119</b> may have a dedicated discrete air supply. The clipper <b>25</b><i>c </i>can include on-board air supply conduits/lines with valves that releasably connect to an air supply. The air supply can be provided at any desired operating pressure sufficient to run the actuators (for holding stations <b>14</b> and/or clipper <b>25</b><i>c</i>) at a desired speed, typically at a pressure between about 80-125 psi.

As noted above, in operation, the respective holding stations <b>14</b> can be configured to stop for a defined time at a respective workstation, index a defined distance, then stop again, and repeat this “stop and go” operation to travel the entire travel path <b>10</b><i>p </i>to serially present different holding members <b>14</b> at each respective workstation along the path <b>10</b><i>p</i>. The system <b>10</b> can be configured to automatically repeatedly index a holding station <b>14</b><i>a </i>desired distance (or angular movement) every 1-20 seconds, typically about every 2-8 seconds, and more typically about every 3-5 seconds. Thus, at each workstation <b>15</b><i>w</i>-<b>35</b><i>w</i>, a respective holding station <b>14</b> can stop for a defined amount of time, index to a next location, stop for the same amount of time (e.g., about 2-8 seconds), index to the next location, etc. to travel about the entire travel path <b>10</b><i>p</i>. In some embodiments, the automatic indexing can be in response to an electronic “go” direction to the drive system as determined by a servo and/or controller in response to sensors, monitors or other input parameters/signals at/from each functional workstation, e.g., a bird is loaded at position <b>1</b> (typically dropped a few inches from a shackle), the hocking is complete at position <b>2</b>, the clipping is complete at position <b>3</b> and a bag is loaded at position <b>4</b> or <b>5</b> (<figref idref="DRAWINGS">FIGS. 5</figref>, <b>1</b>, respectively). In yet other embodiments, the holding stations <b>14</b> can continuously rotate or translate (and components of the workstations may be configured to translate at a common speed for a defined distance to carry out defined operations). The system <b>10</b> can be configured to automatically package between about 10-50 birds a minute, typically about 30, although greater and lesser numbers may be possible.

In some embodiments, such as where the system <b>10</b> includes eight (8) holding stations <b>14</b> (e.g., <figref idref="DRAWINGS">FIG. 1</figref>) and the travel path is substantially circular, each holding station indexed translation can be between about 15-45 degrees. For five (5) holding stations <b>14</b> (e.g., <figref idref="DRAWINGS">FIGS. 5</figref>, <b>10</b>, <b>23</b>A) with a substantially circular travel path <b>10</b><i>p</i>, each holding station <b>14</b> can have an indexed translation of about 72 degrees.

As shown in <figref idref="DRAWINGS">FIGS. 1-3</figref> and <b>5</b>, each holding station <b>14</b> can include a pair of spaced apart arms <b>16</b>₁, <b>16</b>₂that each hold a downwardly extending horn member <b>17</b>. In operation, the horn members <b>17</b> extend inside an open bag <b>40</b> (see, e.g., <figref idref="DRAWINGS">FIG. 4</figref>). The horn members <b>17</b> can include an upper portion <b>17</b><i>u </i>that tapers inwardly a distance to merge into a long portion <b>17</b><i>l</i>. The long portion can be sized and configured to reside inside a respective bag <b>40</b> (<figref idref="DRAWINGS">FIG. 4</figref>) and the upper portion <b>17</b><i>u </i>of the pairs of horn members <b>17</b> can act as a funnel or chute <b>17</b><i>ch </i>(<figref idref="DRAWINGS">FIG. 3</figref>, <b>5</b>) to direct the object to be packaged into the open bag <b>40</b>. <figref idref="DRAWINGS">FIGS. 20A and 20B</figref> illustrate another embodiment of the horn members <b>17</b> and will be discussed further below.

As shown in <figref idref="DRAWINGS">FIGS. 2 and 6</figref>, the lower end portion of the horn members <b>17</b> reside proximate an aligned platform <b>23</b> with an open center space. The bag <b>40</b> can extend downwardly through this space.

In some embodiments, as shown in <figref idref="DRAWINGS">FIGS. 2-4</figref>, the holding station <b>14</b> can include a base <b>24</b> that is aligned with a respective pair of the horn members <b>17</b> to hold the bag <b>40</b> and, when loaded, the object (e.g., poultry) in the bag <b>40</b>. The base <b>24</b> may include at least one upwardly sidewall (shown as two, an inner and outer sidewall) for helping to hold the object/bag <b>40</b> in position. Where used, as shown, the inner sidewall <b>24</b><i>u </i>may be shorter than the outer sidewall.

[In other embodiments, the holding stations <b>14</b> can include a pair of clamps <b>23</b><i>c </i>that close toward each other to hold the object in the bag <b>40</b>. The clamps <b>23</b><i>c </i>can be mounted to the platform <b>23</b> or other mounting member (see, e.g., <figref idref="DRAWINGS">FIGS. 10-15</figref>) and may reside in the center open space thereof (<figref idref="DRAWINGS">FIG. 5</figref>). Combinations of a base and clamps or other clamps and/or components may also or alternatively be used. That is, it is contemplated that other releasably configured holding members/configurations may be used. The platforms <b>23</b>, clamps <b>23</b><i>c </i>and/or bases <b>24</b> can be configured to automatically travel up and down at various locations along the travel path as discussed above. In operation, in some embodiments, the bag <b>40</b> can be pulled off the horn members <b>17</b> of a respective station <b>14</b> between the hocking workstation <b>20</b><i>w </i>and clipper workstation <b>25</b><i>w </i>while clamped via clamps <b>23</b><i>c. </i>

The arms <b>16</b>₁, <b>16</b>₂can be pivotably connected to a linkage <b>18</b> in communication with an actuator <b>19</b>. The actuator <b>19</b> can be connected to a controller <b>200</b> (<figref idref="DRAWINGS">FIG. 10</figref>) (e.g., HMI) that automatically controls when to move the arms <b>16</b>₁, <b>16</b>₂. The arms <b>16</b>₁, <b>16</b>₂can move inward and outward a distance relative to each other via the actuator <b>18</b> and an automated control/drive system (the spacing can be adjusted according to size of the bag and/or object for packaging and/or to provide the desired spacing for different operations such as to cooperate with the hocking station). Pneumatic, hydraulic or electrical lines for the actuators <b>18</b> can reside inside the column <b>12</b>.

Referring to <figref idref="DRAWINGS">FIGS. 1-4</figref>, the bases <b>24</b> can rotate independently of the arms/horn members <b>16</b>₁, <b>16</b>₂/<b>17</b>, but typically the base <b>24</b> and the corresponding arms/horn members <b>16</b>₁, <b>16</b>₂, <b>17</b> rotate together about the travel path <b>10</b><i>p</i>. The base <b>24</b> and arms/horn members <b>16</b>₁, <b>16</b>₂, <b>17</b> can include separate (and synchronized) drive systems for the travel path <b>10</b><i>p </i>or each can be attached together and use the same drive system.

The clamps <b>23</b><i>c </i>can rotate independently of the arms/horn members <b>16</b>₁, <b>16</b>₂/<b>17</b>, but typically also rotate with the corresponding arms/horn members <b>16</b>₁, <b>16</b>₂, <b>17</b> about the travel path <b>10</b><i>p</i>. The platforms <b>23</b>, clamps <b>23</b><i>c </i>(<figref idref="DRAWINGS">FIG. 17A</figref>) and arms/horn members <b>16</b>₁, <b>16</b>₂, <b>17</b> can include separate (and synchronized) drive systems for the travel path <b>10</b><i>p </i>or each can be attached together and use the same drive system.

An inner portion of the platform <b>23</b> can be attached to the platform <b>11</b> via the center column <b>12</b>. The platform <b>23</b> can also be attached to the base <b>24</b>. Thus, rotation of the column <b>12</b> can rotate the bases <b>24</b>. Alternatively, the bases <b>24</b> and/or platforms <b>23</b> (without the bases and/or with the clamps <b>23</b><i>c</i>) can be mounted to the column <b>12</b> and rotate relative to the column via a drive system such as a linkage, belt, chain, rails, gears, rollers and the like.

In some embodiments, as shown for example in <figref idref="DRAWINGS">FIG. 5</figref>, the platforms <b>23</b> can be (indirectly) attached to a pair of the arms <b>16</b>₁, <b>16</b>₂and can rotate based on rotation of the arms. The arms <b>16</b>₁, <b>16</b>₂can rotate based on a drive system that rotates the column <b>12</b> or the arms <b>16</b>₁, <b>16</b>₂can rotate about the column <b>12</b> using a drive system, e.g., linkage, chain, rails, gears, rollers and the like.

The system <b>10</b> can be configured so that each base <b>24</b> (<figref idref="DRAWINGS">FIG. 2</figref>) (where used) and/or clamping mechanism <b>23</b><i>m </i>(<figref idref="DRAWINGS">FIG. 8</figref>, <b>17</b>A) is connected to the mounting frame <b>11</b> (<figref idref="DRAWINGS">FIG. 8</figref>, <b>17</b>A). The mounting assembly can comprise an inline chain and rollers (not shown) with two separation points that allow a respective base <b>24</b> and/or clamp mechanism <b>23</b><i>c </i>to automatically lower and rise with respect to the column <b>12</b> and/or aligned arms <b>16</b>₁, <b>16</b>₂at various locations along the travel path <b>10</b><i>p </i>as was discussed above.

In some embodiments, as shown in <figref idref="DRAWINGS">FIGS. 8 and 17A</figref>, an actuation cylinder <b>119</b> with an upwardly and downwardly translating rod <b>119</b><i>r </i>can be attached to a pivoting bracket <b>23</b><i>b </i>that can automatically extend and retract the clamping mechanism <b>23</b><i>m </i>(with platform <b>23</b> and clamps <b>23</b><i>c</i>). Although not shown in <figref idref="DRAWINGS">FIGS. 1-4</figref>, a similar actuator and rod assembly can be used to translate the base <b>24</b>. In other embodiments, the up and down translation can be carried out using other electromechanical configurations such as, for example, a pair of rails that the base <b>24</b> and/or clamp mechanism <b>23</b><i>m </i>can slide up and down on for the desired rise/drop movements and the like.

In other embodiments, the bases <b>24</b> and/or clamps <b>23</b><i>c </i>of the respective holding stations <b>14</b> can rotate about the travel path <b>10</b><i>p </i>while the arms <b>16</b>₁, <b>16</b>₂of the holding stations <b>14</b> translate back and forth a defined distance without traveling the entire path. In yet other embodiments, after the hocking workstation <b>20</b><i>w</i>, the clamping mechanism <b>23</b><i>c </i>can lower and the corresponding arms/horn members <b>16</b>₁, <b>16</b>₂, <b>17</b> can rotate ahead independently of the clamping mechanism <b>23</b><i>c </i>and/or base <b>24</b> to advance to the bag loading station <b>35</b><i>w </i>where it can be mated to another clamping mechanism <b>23</b><i>c </i>and/or base <b>24</b>, then continue on to the object loading station, then the hocking station. Thus, the clamping mechanism <b>23</b><i>c </i>and/or base <b>24</b> can provide the bag/poultry support only for the bag loading, object loading and hocking stations. Therefore, there may be a lesser number of the arms/horn members <b>16</b>₁, <b>16</b>₂, <b>17</b> than the clamping mechanisms <b>23</b><i>c. </i>

Turning again to <figref idref="DRAWINGS">FIGS. 1 and 2</figref>, in some embodiments, the system mounting frame <b>11</b> can include a polygonal collar <b>111</b>, as shown an octagon for holding eight (8) stations <b>14</b>. Other embodiments can use other shapes such as, for example, a hexagon for 5 stations <b>14</b>. <figref idref="DRAWINGS">FIGS. 10-15</figref> illustrate yet other frame <b>11</b> configurations that cooperate with the center column <b>12</b>.

In some embodiments, some sides of the system <b>10</b> can be “blank”, e.g., not hold a station <b>14</b> (not shown). The collar <b>111</b> can be attached to the column <b>12</b>. The arms <b>16</b>₁, <b>16</b>₂can be attached to the collar <b>111</b> and extend outwardly therefrom. Typically, the collar <b>111</b> is stationary or rotates with the stations <b>14</b>, depending on the drive system and translation configuration used. A similar collar <b>111</b> can be used to support the base <b>24</b>. However, other mounting configurations can be used to support the arms <b>16</b>₁, <b>16</b>₂of each station <b>14</b> and/or the clamping mechanisms <b>23</b><i>c. </i>

<figref idref="DRAWINGS">FIG. 5</figref> shows that the actuators <b>19</b> for respective pairs of arms <b>16</b>₁, <b>16</b>₂can all radially extend outward from the center column <b>12</b> or centerline <b>12</b><i>c </i>of the mounting platform/travel path <b>10</b><i>p</i>. The inner end portions of the actuators <b>19</b> can reside closely spaced apart such that the actuators extend outwardly in five equally spaced legs to form a five-leg “star” like shape when viewed from the top.

Referring again to <figref idref="DRAWINGS">FIG. 5</figref> (and <figref idref="DRAWINGS">FIG. 10</figref>), as shown, the loading station <b>35</b><i>w </i>has two load (bag dispensing) portions <b>35</b>₁, <b>35</b>₂. The loader <b>35</b>L is configured to allow the sides to rotate about 180 degrees. Thus, in some embodiments, the bag loading station <b>35</b><i>w </i>is a dual station loader <b>35</b>L allowing for a 180 degree rotational setup. Bags can be loaded on one side of the dual bag station while the machine is running in normal operation mode using the other side of the dual bag dispensing station. The loading portions <b>35</b>₁, <b>35</b>₂can each hold sets of wicked bags (typically at least about 120 pre-wicked bags). Examples of wicked bags with absorption pads will be discussed with respect to <figref idref="DRAWINGS">FIG. 16C</figref>. The dual bag loader <b>35</b>L can automatically rotate the loaded side into position for use and the empty side into position for reloading. Once the empty side is rotated out of operative position, the system <b>10</b> can continue with normal operation. In some embodiments, the loader <b>35</b>L or system <b>10</b> can monitor when to rotate the loader so that the rotation is performed while stations <b>14</b> are moved between stations so that rotation of the loader <b>35</b>L does not slow down or change operation of the system <b>10</b>. More bags <b>40</b> can be refilled on the “empty” side <b>35</b>₁while the system <b>10</b> is running with the other side <b>35</b>₂, readying the dual bag station for another rotation.

Turning now to <figref idref="DRAWINGS">FIGS. 6</figref>, <b>9</b> and <b>10</b>, <b>12</b>, <b>18</b>A, <b>18</b>B exemplary pushing and hocking workstations <b>20</b><i>w </i>are shown. A receiving plate <b>20</b><i>p </i>is attached to an actuation (air) cylinder <b>20</b><i>a </i>that rises and allows the bagged bird or other object to rest on it. Once in position, the object in the bag, e.g., chicken, is resting on the receiving plate <b>20</b><i>p</i>, where the bird automatically gets hocked. As shown, the workstation <b>20</b><i>w </i>can also include an aligned pusher <b>21</b> with a pusher block <b>21</b><i>b </i>in communication with an actuator <b>21</b><i>a</i>. This pusher block <b>21</b><i>b </i>is sized and configured to enter into the bag and press the legs of the poultry (e.g., chicken) up against the body (of the chicken), referred to as “hocking the legs”. While the pusher block <b>21</b><i>b </i>has the legs hocked, the bird is clamped, typically via clamps <b>23</b><i>c</i>, from both sides to hold it in position. Additional or alternative air-cylinder driven clamps may be used to hold the hocked legs in place. While the bird is being held or clamped via clamps <b>23</b><i>c</i>, the pusher block <b>21</b><i>b </i>and the receiving plate <b>20</b><i>p </i>retract to their original (“home”) positions (<figref idref="DRAWINGS">FIGS. 7</figref>, <b>18</b>B, <b>19</b>A). The system <b>10</b> then rotates the holding station <b>14</b> from position <b>2</b> to position <b>3</b>, while the bird is held in the hocked position, typically by side clamps. In other embodiments, a clamp can be attached to the bag and/or in the bag (and can even be packaged with the whole bird in the bag) to provide the clamping force. <figref idref="DRAWINGS">FIGS. 23A-23D</figref> illustrate that the workstation <b>20</b><i>w </i>is a pushing workstation which cooperates with a hocking unit that is integrated into the translating (clamp) stations <b>14</b>.

Comparing <figref idref="DRAWINGS">FIGS. 6 and 7</figref> and referring to <figref idref="DRAWINGS">FIG. 13</figref> the holding stations <b>14</b> at the hocking station <b>20</b><i>w</i>, clipping workstation <b>25</b><i>w </i>(and bag loading workstation <b>35</b><i>w</i>) in <figref idref="DRAWINGS">FIG. 6</figref> are elevated relative to the position in <figref idref="DRAWINGS">FIG. 7</figref> and similarly in <figref idref="DRAWINGS">FIG. 13</figref>, for example. That is, the clamps <b>23</b><i>c </i>reside above a pivot attachment <b>22</b><i>p </i>in <figref idref="DRAWINGS">FIG. 6</figref> and below the pivot attachment <b>22</b><i>p </i>in <figref idref="DRAWINGS">FIG. 7</figref> (and similarly in <figref idref="DRAWINGS">FIGS. 11-15</figref> depending on the desired height at different workstations). Thus, <figref idref="DRAWINGS">FIG. 7</figref> illustrates an exemplary “drop zone”.

In some embodiments, while the bird is still clamped via clamps <b>23</b><i>c</i>, the bird and clamped portion drop to a different height, readying it for the clipping at workstation <b>25</b><i>w </i>at Position <b>3</b> (<figref idref="DRAWINGS">FIG. 1</figref>) or Position <b>4</b> (<figref idref="DRAWINGS">FIG. 5</figref>, <b>10</b>). This lowered position allows for the tail end of the bag to be inserted into clipper <b>25</b><i>c</i>. The system <b>10</b> typically serially rotates the respective holding stations <b>14</b> to the clipping workstation <b>25</b><i>w </i>after the clamps <b>23</b><i>c </i>of a respective station <b>14</b> drop into the lower position, but the clamps <b>23</b><i>c </i>can drop while rotating or after in the clipper workstation. Also, the clipper <b>25</b><i>c </i>may be oriented at an elevated level not requiring a change in elevation of the bag/object. Once in the clipper <b>25</b><i>c</i>, the bag tail is gathered, a clip is applied, the knife fires, cutting the bag tail loose from the packaged bird, and the tail is removed by a blower or a vacuum system, or the like. The system <b>10</b> indexes again. During the rotation from the clipping workstation <b>25</b><i>w </i>to the next location or while stopped (e.g., from or between position <b>3</b> to position <b>4</b> in <figref idref="DRAWINGS">FIG. 1</figref> or from or between position <b>4</b> to position <b>5</b> in <figref idref="DRAWINGS">FIG. 5</figref>), the packaged bird is released, dropping it on a takeaway conveyor or other receiving member (which may be supplied by the customer) or may be provided as an integrated system component.

<figref idref="DRAWINGS">FIG. 8</figref> illustrates a holding station <b>14</b> in the lowered configuration and an exemplary clamping mechanism <b>23</b><i>m</i>. As shown, the clamping mechanism <b>23</b><i>m </i>includes a bracket <b>23</b><i>b </i>with at least one linkage <b>22</b><i>l </i>that is pivotably attached <b>22</b><i>a </i>at a first end portion to the clamp platform <b>23</b> and pivotably attached <b>22</b><i>p </i>at the second opposing end to the column <b>12</b>. The actuator <b>119</b> is attached to the linkage <b>22</b><i>l </i>and extends up and down to cause the clamps to rise and lower at desired times. As shown in <figref idref="DRAWINGS">FIG. 9</figref>, the bracket <b>23</b><i>b </i>includes two linkage assemblies with a pair of links, one linkage assembly <b>22</b><i>l </i>residing above the other, that controllably move the clamps <b>23</b><i>c </i>in response to actuation of the cylinder <b>119</b>.

<figref idref="DRAWINGS">FIGS. 17A and 17B</figref> illustrate a different clamp mechanism <b>23</b><i>c </i>and does not require a platform <b>23</b> nor base <b>24</b>. As shown, the clamping mechanism <b>23</b><i>m </i>includes a vertical plate <b>123</b> which holds a pair of clamps <b>23</b><i>c </i>on rails <b>123</b><i>r </i>which reside in slots <b>123</b><i>s</i>. The clamps <b>23</b><i>c </i>are in communication with an actuator that directs the clamps to move together or apart. The clamps <b>23</b><i>c </i>slide via the rail and slot configuration in toward each other about the package and outwardly away from each other. As is shown, the clamps <b>23</b><i>c </i>can each include upper and lower (vertically spaced apart) gripping members <b>124</b>. As with the platform <b>23</b>, the plate <b>123</b> can be attached to the center column <b>12</b> via pivoting linkages <b>22</b><i>l </i>and are in communication with an actuator <b>119</b> so as to be able to rise and lower a defined distance at different workstations or locations about the travel path <b>10</b><i>p. </i>

For safety, a perimeter frame <b>11</b> (also shown as polygonal in <figref idref="DRAWINGS">FIGS. 1 and 2</figref> and more rectangular in <figref idref="DRAWINGS">FIGS. 10-15</figref>) can extend about the travel path <b>10</b> proximate the outer reach of the arms <b>16</b>₁, <b>16</b>₂of the holding stations <b>14</b> and rotate with or remain stationary with respect to the holding stations <b>14</b>.

As noted above, <figref idref="DRAWINGS">FIGS. 10-15</figref> illustrate a similar system <b>10</b> to that discussed with respect to <figref idref="DRAWINGS">FIGS. 5-9</figref>. However, the clamp mechanism <b>23</b><i>c </i>is configured to slide transversely on rails <b>123</b><i>r </i>held in slots <b>123</b><i>s </i>a and the clamp configuration is such that no base <b>24</b> is required (but may optionally be used). In addition, as shown, the receiving station <b>15</b><i>w </i>includes a funnel <b>15</b><i>f. </i>

As shown in <figref idref="DRAWINGS">FIGS. 16A and 16B</figref>, the bag loading station <b>35</b><i>w </i>is configured to hold wicketed bags <b>40</b><i>w </i>(<figref idref="DRAWINGS">FIG. 15C</figref>). Sets of stacked bags <b>40</b> can be held by member <b>135</b>. The bag loading station <b>35</b><i>w </i>can automatically peel one bag off the set and place it over the horn members <b>17</b> (<figref idref="DRAWINGS">FIG. 20A</figref>, <b>20</b>B). The bag loading station <b>35</b><i>w </i>can include slide rails <b>136</b> that translate the holding member <b>135</b> up and down. The bag loading station <b>35</b><i>w </i>can rotate the two bag holders <b>35</b>₁, <b>35</b>₂to present a loaded set when one set is depleted or empty as discussed above. <figref idref="DRAWINGS">FIG. 16A</figref> shows the bag loading member <b>135</b> lowered when communicating with a station <b>14</b> while <figref idref="DRAWINGS">FIG. 16B</figref> shows a respective member <b>135</b> raised for reloading (<figref idref="DRAWINGS">FIG. 16B</figref>). However, as noted above the station <b>35</b><i>w </i>need not raise or lower the holders <b>135</b> which can be kept at a defined level and aligned with holder stations <b>14</b> that rotate into communication with the workstation <b>35</b><i>w</i>. It is contemplated that at normal operating speed, bags may be reloaded every 3-10 minutes, typically every 3-5 minutes for 120 wicketed bags <b>40</b><i>w</i>. It is also noted that the bag loading station <b>35</b><i>w </i>is shown as having two loaders <b>35</b>₁, <b>35</b>₂that alternatively move into operative position, but a single one or more than two may also be used.

<figref idref="DRAWINGS">FIGS. 16C and 16D</figref> illustrate an example of a bag with a pad <b>40</b><i>p </i>for soaking up liquid and for inhibiting punctures from sharp neck bones (e.g., a wicketed bag) <b>40</b><i>w</i>. Suitable bags are available commercially from Bemis Company located in Neenah, Wis. However, to improve the operation of the bag loading station <b>35</b><i>w </i>it is contemplated that the bag <b>40</b><i>w </i>can be configured with angled slits <b>42</b> that extend from a top primary edge of the bag rather than a circular opening as is conventional. <figref idref="DRAWINGS">FIG. 16C</figref> illustrates that the slits or perforations <b>42</b> can be offset from a centerline of a circular opening. <figref idref="DRAWINGS">FIG. 16D</figref> illustrates that the slits <b>42</b> can be angled and extend from a top edge to a distance that is about 0.25-1.25 inches inward thereof. The slits can be a continuous slit or may be perforated for easy tearing.

<figref idref="DRAWINGS">FIGS. 20A and 20B</figref> illustrate a horn assembly <b>170</b> similar to that shown with respect to <figref idref="DRAWINGS">FIGS. 2 and 5</figref>. In this embodiment, the horn members <b>17</b> are configured to close together and move apart a defined distance to snugly hold a bag <b>40</b> thereon (the horn members have a length that extends into the bag). In the spaced apart position, the horn members <b>17</b> cooperate with a bag <b>40</b> held therearound so that the bag <b>40</b> is stretched to define a substantially oval shape <b>40</b> (<figref idref="DRAWINGS">FIG. 20B</figref>) at the upper portion thereof. As shown, the horn members <b>17</b> each include semi-circular upper portions <b>17</b><i>u </i>which can be described as a substantially “C” shape <b>17</b><i>c</i>. When positioned close together as shown in <figref idref="DRAWINGS">FIG. 20A</figref>, one outer leg <b>17</b><i>o </i>of each “C” shape <b>17</b><i>c </i>extends a distance beyond that of an adjacent inner leg <b>17</b><i>i </i>of the other “C” shape <b>17</b><i>c</i>. The system <b>10</b> an automatically move the horn members <b>17</b> apart to the spaced apart configuration (<figref idref="DRAWINGS">FIG. 20B</figref>) which stretch/extend the bag <b>40</b>. The open shape corresponds to a shape of the whole bird for ease of transfer from a shackle system while the closed shape is more compact for ease of loading the bag. The horn members <b>17</b> may reside in the position of <figref idref="DRAWINGS">FIG. 20A</figref> or in a different but closer configuration than that shown in <figref idref="DRAWINGS">FIG. 20B</figref> after the whole bird is in the bag, such as after the hocking workstation <b>20</b><i>w </i>(or after the hocking operation is complete) and before the clipper station <b>25</b><i>w </i>(or before the clipper operation at the clipper workstation).

In operation, in some embodiments, the bag <b>40</b> can be pulled off the horn members <b>17</b> between the hocking workstation <b>20</b><i>w </i>and clipper workstation <b>25</b><i>w </i>while clamped via clamps <b>23</b><i>c. </i>

Referring now to <figref idref="DRAWINGS">FIG. 21</figref>, the system <b>10</b> can include a drive system <b>50</b> with a motor <b>50</b>M that drives the drive mechanism to translate the center post <b>12</b> and/or translate each base <b>24</b> or clamping mechanism <b>23</b><i>m </i>(in concert) and/or arms <b>16</b>₁, <b>16</b>₂of the product holding stations <b>14</b> through the travel cycle along the travel path <b>10</b><i>p</i>. The system <b>10</b> can include at least one controller <b>200</b> (e.g., a central processor or more than one controller or processor or Application Specific Integrated Circuit “ASIC”) that directs the operation of the system, including, for example, the operations of the workstations, the movement of the holding stations <b>14</b> (speed and stop/start times or index/translation distances and the like). The speed of the system <b>10</b> can be synched to the input speed of the conveyor/shackle system <b>100</b>. The controller <b>200</b> can also monitor defined operational conditions, such as over-temperatures, pressures, proximity sensors and the like to automate the operation and reduce manual labor requirements. <figref idref="DRAWINGS">FIG. 6</figref> illustrates the holding station drive control <b>50</b><i>c </i>as a separate circuit or module <b>50</b><i>c</i>, but it can be integrated into one module or processor or split into more than one circuit, module or processor and the like. Similarly, the holding station control and monitoring circuit or module <b>210</b> and the workstation control and sensor monitoring circuit and/or module <b>215</b> are shown as separate from the controller <b>200</b> and each other for ease of discussion. However, the function of each of these circuits and modules can be combined or split into other subsystems or circuits/modules (including remote or local circuits and/or modules).

<figref idref="DRAWINGS">FIG. 21</figref> also illustrates that the controller <b>200</b> can include an internet interface <b>2001</b> that allows a remote user to access the system for upgrades, diagnosis or repairs.

The controller <b>200</b> can comprise a Human Machine Interface (HMI) that is in communication with the drive system <b>50</b> and that can comprise an adjustable drive input control circuit with the drive speed being electronically and/or programmatically adjustable as well as the “stop and go” increments being electronically and/or programmatically adjustable.

In some embodiments, the system <b>10</b> can communicate with the input feed system <b>100</b> such as via a wireless (or wired) interface <b>100</b><i>c </i>to interactively control the speeds of each system <b>100</b>, <b>10</b> to facilitate efficient loading. The interface <b>100</b><i>c </i>can be provided using a local area network or a global computer network that allows the systems to communicate. For example, if the speed S₁of system <b>100</b> increases, the speed S₂of the rotation of the holding stations <b>14</b> can increase accordingly. If the system <b>100</b> shuts down, stops, pauses or goes into a “sleep mode” for a operational problem or shift change, then the system <b>10</b> may also shut down, stop, pause or go into a “sleep mode” (the latter refers to an operating condition whereby the equipment is not turned off, but less energy is used than an active operational mode).

<figref idref="DRAWINGS">FIG. 22</figref> illustrates an exemplary layout of a packaging system <b>110</b> using a plurality of (rotating) systems <b>10</b> spaced apart about the input conveyor/shackle <b>100</b>, shown as four systems <b>10</b>₁-<b>10</b>₄, but lesser or greater numbers can be used. Thus, two or more systems <b>10</b> can be in communication with one input conveyor system. Indeed, one system <b>10</b> can be in communication with two input conveyor systems <b>100</b> spaced diametrically apart (not shown) using alternating stations that take and package from the different conveyors. One or more controllers <b>200</b> can be used to direct the operations of the systems <b>10</b>₁-<b>10</b>₄.

<figref idref="DRAWINGS">FIGS. 23A-23D</figref> illustrate a system <b>10</b> similar to that shown in <figref idref="DRAWINGS">FIG. 10</figref>. However, in this embodiment, hocking components are integrated into the holding stations <b>14</b>. Thus, in this embodiment, the station <b>20</b><i>w </i>can include a stationary pushing mechanism <b>21</b> with a pushing member <b>21</b> that pushes down from the top (e.g., like <figref idref="DRAWINGS">FIG. 6</figref>), but does not include other hocking components (e.g., the lower pushing mechanism <b>20</b> shown in <figref idref="DRAWINGS">FIG. 6</figref>). Thus, each translating holding station <b>14</b> includes integrated hocking components (see, e.g., <figref idref="DRAWINGS">FIGS. 24A</figref>, <b>24</b>B) that cooperate with the pushing mechanism <b>21</b> at the workstation <b>20</b><i>w </i>to carry out the pushing/hocking operation. <figref idref="DRAWINGS">FIGS. 25A and 25B</figref> illustrate an example of a pushing station <b>20</b><i>w </i>that serially engages with respective holding stations <b>14</b> each having onboard hocking components <b>24</b><i>p</i>, <b>216</b>, <b>220</b>.

Referring to <figref idref="DRAWINGS">FIGS. 24A</figref>, <b>24</b>B, the holding stations <b>14</b> can each include back plates <b>220</b> that swing in from a back side of the bag <b>40</b> against the poultry and a pair of cooperating fingers <b>216</b> that close against legs of the poultry on the front side of the bag. The fingers <b>216</b> and back plates <b>220</b> can be synchronized to close against the different sides of the poultry at substantially the same time so that the bag <b>40</b> with the poultry is substantially centered over or on the base plate <b>24</b><i>p</i>. To facilitate a snug hold, the fingers <b>216</b> and back plates <b>220</b> can remain in the capture/hold configuration as the respective stations travel to the clipper station <b>25</b><i>w</i>. The fingers <b>216</b> and back plates <b>220</b> can be used as the clamp mechanism <b>23</b><i>m </i>of the stations <b>14</b>. Thus, the clamp mechanism <b>23</b><i>m </i>will clamp front to back instead of side-to-side (<figref idref="DRAWINGS">FIGS. 9</figref>, <b>17</b>A, <b>17</b>B). In other embodiments, a four-way clamp system may also be used (not shown).

As also shown in <figref idref="DRAWINGS">FIGS. 24A and 24B</figref>, the holding stations <b>14</b> can include a pair of upwardly extending sidewalls <b>23</b><i>w </i>that form a portion of a “cradle” on each side of the plate <b>24</b><i>p</i>. As described for other embodiments, the holding station <b>14</b> can also include an actuator <b>119</b> and linkages <b>22</b><i>l </i>that are able to move the base plate <b>24</b><i>p </i>and other mounted components up and down.

The base <b>24</b> can comprise a plate <b>24</b><i>p </i>that is spring-loaded <b>24</b><i>s</i>. As also shown, the base plate <b>24</b><i>p </i>is attached to mounting members <b>224</b><i>m </i>that can slide up and down in slots <b>224</b><i>s</i>. The spring-loaded configuration <b>24</b><i>s </i>can comprise coil springs as shown, or may take the form of resilient blocks, leaf springs, Belleville springs, Clover-Dome spring washers (see, e.g., U.S. Pat. No. 6,705,813), or any other type of flexible elastic member including, for example (polyurethane or other suitable material) O-rings. Combinations of different types of elastic or resilient members and/or more than one of the same type may also be used.

The base plate <b>24</b><i>p </i>can be planar, have a block-like shape, or any other suitable shape. As shown, raised edges <b>24</b><i>e </i>can be provided to help align the bag/poultry in the holding station <b>14</b>. The raised edges <b>24</b><i>e </i>can be provided by a replaceable guide member that attaches to the plate or the features can be integral with the plate, e.g., machined or molded in.

The holding stations <b>14</b> can include linear side actuators <b>219</b> that communicate with the fingers <b>216</b> and back plates <b>220</b>. The back plates <b>220</b> can include an arcuate slot <b>220</b><i>s</i>. The fingers can include an elongate slot <b>216</b><i>s </i>and a pin <b>216</b><i>p </i>that is attached to an underlying support and travels in the slot <b>216</b><i>s </i>as the fingers <b>216</b> open and close (<figref idref="DRAWINGS">FIGS. 24A</figref>, <b>24</b>B). A linkage <b>222</b> can attach each finger <b>216</b> and back plate <b>222</b>. The linkage <b>222</b> can include a downwardly extending pin <b>222</b><i>p</i>₁that travels in the slot <b>220</b><i>s</i>. The linkage <b>222</b> can include a spaced apart upwardly extending pin <b>222</b><i>p</i>₂on an opposing end portion that is pivotably attached to the front portion of the finger <b>216</b>. As the respective linear actuator <b>219</b> pulls the corresponding linkage <b>222</b> outward (<figref idref="DRAWINGS">FIG. 24B</figref>) the fingers <b>216</b> pivot open and the back plates <b>220</b> also pivot open, in concert, to release the trapped bird. In the reverse, the linear actuators <b>219</b> extend to pivot the fingers <b>216</b> to close closer together and cause the back plates to close and move inward closer to the fingers <b>216</b>. However, it is noted that other clamp mechanisms <b>23</b><i>m </i>can be used and the back plates <b>220</b>, where used, can be separately actuated from the fingers <b>216</b>, where used.

<figref idref="DRAWINGS">FIGS. 25A and 25B</figref> illustrate an example of a hocking/pushing station <b>20</b><i>w </i>with the holding station <b>14</b> shown in <figref idref="DRAWINGS">FIGS. 24A and 24B</figref> (and as shown in <figref idref="DRAWINGS">FIGS. 23A-23D</figref>).

For completeness, it is noted that after position <b>2</b> (workstation <b>20</b>), typically between positions <b>2</b> and <b>4</b>, the horn <b>17</b> may disengage the bag <b>40</b> (e.g., retract inward a distance from a perimeter of the bag, raise above the bag and/or close together so as to not push out against the open edge of the bag).

<figref idref="DRAWINGS">FIGS. 26A and 26B</figref> illustrate one example of a clipper workstation <b>25</b><i>w </i>(e.g., position <b>4</b>). This example illustrates a single gate clipper design, but double gate designs may also be used which may change positions and/or configurations of cooperating components (e.g., tail grabs, product pulling device for a tight constant rope diameter and the like). In this embodiment, the station <b>25</b><i>w </i>includes a product bag pulling device <b>125</b> above the clipper <b>25</b><i>c</i>. This device, while not required, helps gather the bag and pull it tight to provide a desired tight and consistent rope diameter. It can also facilitate cutting the excess bag tail off and/or removing it once cut (e.g., via vacuum or the like). As shown, the device <b>125</b> can include a vacuum block <b>125</b><i>b </i>that can pivot between a horizontal and an angled orientation (<figref idref="DRAWINGS">FIGS. 26A</figref>, <b>26</b>B). A vacuum hose can attach to the block <b>125</b><i>b </i>to pull a vacuum and help pull the gathered bag tail.

<figref idref="DRAWINGS">FIGS. 27A-27E</figref> illustrate another configuration of a clipper <b>25</b><i>c </i>suitable for the clipper workstation <b>25</b><i>w</i>. <figref idref="DRAWINGS">FIG. 27A</figref> shows the clipper <b>25</b><i>c </i>with the gates <b>25</b><i>g </i>open, ready to receive a product for clipping. In operation, a product in the bag <b>40</b> rotates around into the open space between the gates of the clipper <b>25</b><i>g</i>. As shown in <figref idref="DRAWINGS">FIG. 27B</figref>, the gates <b>25</b><i>g </i>then close (around the bag to gather it). The block <b>125</b><i>b </i>on top of the clipper <b>25</b><i>c </i>can be configured as a combination vacuum/pusher block which, in some embodiments, can have a twofold function. The bottom of the vacuum block <b>125</b><i>b </i>can act as a pusher, which pushes bag down toward the die of the clipper path per <figref idref="DRAWINGS">FIG. 27C</figref>. Grippers <b>126</b> that reside over the pusher plate <b>125</b><i>b</i>, but above the gates <b>25</b><i>g </i>then close on the bag tail as shown in <figref idref="DRAWINGS">FIG. 27D</figref>. The vacuum block <b>125</b><i>b </i>raises vertically (as indicated by the arrow in <figref idref="DRAWINGS">FIG. 27E</figref>) with grippers still gripping the bag tail, pulling the bag upwards and tight. At this point, the clipper <b>25</b><i>c </i>is ready to clip and cut excess tail off the bag (where cutting is used), completing the cycle. A vacuum is then applied by the vacuum block <b>125</b><i>b </i>to dispose of the bag tail. After the clipped bag with product is released, the clipper <b>25</b><i>c </i>resets back to the configuration shown in <figref idref="DRAWINGS">FIG. 27A</figref> in preparation for the next cycle with a subsequent product held by a holding station <b>14</b>.

<figref idref="DRAWINGS">FIG. 28</figref> illustrates exemplary operations that may be used to carry out methods of packaging objects according to some embodiments of the present invention. As shown, a plurality of spaced apart poultry holders that travel about a closed loop travel path can be provided (block <b>300</b>). The poultry holders are translated in concert so that each respective poultry holder automatically serially travels through a plurality of defined spaced apart workstations residing proximate a perimeter of the travel path, including a hocking workstation and a clipping workstation (block <b>305</b>). A packaged whole bird in a clipped bag is successively provided from respective poultry holders after the poultry holders travel pass (or at) the clipping workstation (block <b>310</b>). The closed loop travel path can optionally be substantially circular, and the translating step is carried out by rotating the poultry holders (in a repeating “stop and go” indexed mode) about a vertically extending centerline (block <b>307</b>).

In particular embodiments, the system <b>10</b> can package whole bird chickens. The speed of the system <b>10</b> can be such that it can provide between about 20-80, typically about 30 bagged, whole birds, per minute. The birds can be packaged using one of two different input systems/methods, depending on the customer's needs. One method can be carried out by receiving the birds from an overhead (over head conveying mechanism, which brings birds to the machine). The other method can be carried out by receiving the birds from a conveying mechanism. An exemplary sequence of operations includes the following for a poultry packaging system (although illustrated using five discrete (four functional) positions, other numbers of positions, functional positions and holding stations can be used and/or some functional positions can be combined at one workstation). It is also noted that the workstations <b>15</b><i>w</i>-<b>35</b><i>w </i>themselves may be configured to travel a define path to cooperate with various holding stations <b>14</b>. That is, the holding stations <b>14</b> may be stationary and the workstations <b>15</b><i>w</i>-<b>35</b><i>w </i>can translate about an endless path about the holding stations <b>14</b> to carry out the desired functions. In yet other embodiments, the holding stations <b>14</b> and the workstations <b>15</b><i>w</i>-<b>35</b><i>w </i>can travel about defined paths to serially cooperate to carry out a series of defined functions (not shown).

Position <b>1</b>: Load and Drop. Chicken is dropped from the moving shackle <b>100</b> into loading chute <b>15</b><i>h </i>and then into horn <b>17</b> holding the bag <b>40</b> open and forming an entry loading chutes <b>17</b><i>ch</i>. The loading chute <b>17</b><i>ch </i>has a pre-loaded bag <b>40</b> from station/position <b>5</b> (<b>35</b><i>w</i>) attached to it. The chicken slides through the loading chute <b>17</b><i>ch </i>into the bag <b>40</b>. Once in the bag, the chicken position is sensed by a proximity sensor, notifying the system <b>10</b> that it is ready to continue. System <b>10</b> automatically rotates (e.g., counter clockwise) to Position/Station <b>2</b>.

Position <b>2</b>: Pushing and Hocking. In one embodiment, the receiving plate <b>20</b><i>p </i>comes up and allows the bagged chicken to rest on it. Once the chicken is resting on the receiving plate <b>20</b><i>p </i>it then gets hocked. A pusher <b>21</b> comes down from above with a pusher block <b>21</b><i>b </i>attached. This pusher block <b>21</b><i>b </i>goes into the bag and presses the chicken legs up against the body of the chicken, e.g., hocking the legs. While the pusher block <b>21</b><i>b </i>has the legs hocked, the bird is clamped from both sides to hold it in position. Additional air cylinder clamps may be used to hold the hocked legs in place. While the bird is being held, the pusher block and the receiving plate retract to their original positions.

In another embodiment, the fingers <b>216</b> and back plates <b>220</b> trap (clamp) the poultry in the bag therebetween while the bag with poultry is supported by the plate <b>24</b><i>p</i>. The pusher <b>21</b> again comes down from the top to extend the pusher block <b>21</b><i>b </i>into the bag and presses the chicken legs up against the body of the chicken, e.g., hocking the legs. The pusher block can extend into the bag before or after the fingers <b>216</b> and/or back plates <b>220</b> are fully deployed. The pusher block is retracted after the hocking is completed.

Machine (holding station <b>14</b>) rotates (from position <b>2</b> to position <b>3</b>), while the bird is being held by its side clamps and/or by the front and back clamps (e.g., fingers and back plates).

Position <b>3</b>: Station Drop. While the bird is still clamped, the bird and clamp mechanism move down to a different height, readying it for the clipping of Position <b>4</b> (<figref idref="DRAWINGS">FIG. 5</figref>). The machine can rotate to Position <b>4</b> after the station <b>14</b> moves into the lower position.

Position <b>4</b>: Clipper Station. This position allows for insertion into the clipper <b>25</b><i>c</i>. Before or after it is in the clipper <b>25</b><i>c</i>, the bag tail is gathered, a clip is applied, the knife fires, cutting the bag tail loose from the packaged bird, and the tail is removed by a blower or a vacuum system, or the like. For example, a vacuum block can pull a vacuum on the bag tail and help gather the bag tail, then pulling excess cut tail away after cutting. A mechanical device can pull the upper portion of the bag to provide a more uniform rope diameter of the bag. Different mechanical devices can be used depending on the clipper type, e.g., single gate or double gate. The system <b>10</b> indexes another time. During the rotation from position <b>4</b> to position <b>5</b>, the packaged bird can be released, typically dropping or placing it on a takeaway conveyor (which may be supplied by the customer). Manual or other automated removal may be used.

Position <b>5</b>: Bag Loading Station. The bag loading station can be a dual station <b>35</b>L with 180 degree rotational setup. Bags <b>40</b> (e.g., connected lengths of bags) can be loaded on one side of the dual bag station while the system <b>10</b> is running in normal operation mode, using the other side of the dual bag station. The dual bag station, where used, will rotate the recently loaded side into position for use and the empty side into position for reloading. Once the station is rotated, the machine will continue with normal operation. More bags can be refilled while the machine is running, readying the dual bag station for another rotation.

The machine then indexes once more to complete the revolution (e.g., a single rotation of the endless travel path). While indexing from Position <b>5</b> to Position <b>1</b>, the side-to-side and/or front-to-back clamps <b>23</b><i>c </i>lift back up the distance the clamps <b>23</b><i>c </i>of the respective holding station <b>14</b> dropped in position <b>3</b>. Once the “empty” holding station <b>14</b> arrives at Position <b>1</b>, the system <b>10</b> is ready for another bird.

The systems <b>10</b> can accept user input to select the desired product and the system can automatically electronically implement different parameters such as different drive speeds, table position, input device speed, desired clipper activation speed, holding station drop and raising speed and/or drop distance and the like.

The system <b>10</b> can be Ethernet ready for remote access via VPN and may also be PROFIBUS ready, foreign language supported. <figref idref="DRAWINGS">FIGS. 23A-23D</figref> illustrate a top box <b>510</b> which houses a circuit that operates using an Ethernet signal to provide the Internet interface and to communicate with (e.g., controls) valves associated with the system <b>10</b>. The box <b>510</b> may reside over a rotary union box <b>505</b> with airlines to pneumatic components of the system <b>10</b>. A larger box <b>500</b> can house the valves associated with the operation of the drive and station actuators. The box <b>500</b> can rotate with the center column. The Ethernet and rotary union boxes may be static (non-rotational).

In some embodiments, the system <b>10</b> can be configured to operate with an automated synchronized drive control system that may use a single virtual axis for ramp-up to maximum operational speed drive system can operate at a selected (variable or constant) speed.

The system <b>10</b> can be configured with an automatic positioning using a touchscreen input on the HMI (human/machine interface) display.

<figref idref="DRAWINGS">FIG. 29</figref> is a block diagram of exemplary embodiments of data processing systems that illustrates systems, methods, and computer program products in accordance with embodiments of the present invention. The processor <b>410</b> communicates with the memory <b>414</b> via an address/data bus <b>448</b>. The processor <b>410</b> can be any commercially available or custom microprocessor. The memory <b>414</b> is representative of the overall hierarchy of memory devices containing the software and data used to implement the functionality of the data processing system. The memory <b>414</b> can include, but is not limited to, the following types of devices: cache, ROM, PROM, EPROM, EEPROM, flash memory, SRAM, and DRAM.

As shown in <figref idref="DRAWINGS">FIG. 29</figref>, the memory <b>414</b> may include several categories of software and data used in the data processing system <b>405</b>: the operating system <b>452</b>; the application programs <b>454</b>; the input/output (I/O) device drivers <b>458</b>; the Automated Control and Holding Station Drive Module <b>450</b> and/or Workstation Control Module <b>449</b>; and the data <b>456</b>.

The data <b>456</b> may include synch adjustments, drive speeds, clipper set-up information, and the like, corresponding to particular or target products or input parameters for one or more producers. The data <b>456</b> may include a synchronized drive module for synchronizing the drive speeds of the different cooperating systems, e.g., holding support (column) drive system and the like.

As will be appreciated by those of skill in the art, the operating system <b>452</b> may be any operating system suitable for use with a data processing system, such as OS/2, AIX, DOS, OS/390 or System390 from International Business Machines Corporation, Armonk, N.Y., Windows CE, Windows NT, Windows95, Windows98 or Windows2000 from Microsoft Corporation, Redmond, Wash., Unix or Linux or FreeBSD, Palm OS from Palm, Inc., Mac OS from Apple Computer, LabView, or proprietary operating systems. The I/O device drivers <b>458</b> typically include software routines accessed through the operating system <b>452</b> by the application programs <b>454</b> to communicate with devices such as I/O data port(s), data storage <b>456</b> and certain memory <b>414</b> components and/or the dispensing system <b>420</b>. The application programs <b>454</b> are illustrative of the programs that implement the various features of the data processing system <b>405</b> and preferably include at least one application which supports operations according to embodiments of the present invention. Finally, the data <b>456</b> represents the static and dynamic data used by the application programs <b>454</b>, the operating system <b>452</b>, the I/O device drivers <b>458</b>, and other software programs that may reside in the memory <b>414</b>.

While the present invention is illustrated, for example, with reference to the Modules <b>449</b>, <b>450</b> being an application program in <figref idref="DRAWINGS">FIG. 29</figref>, as will be appreciated by those of skill in the art, other configurations may also be utilized while still benefiting from the teachings of the present invention. For example, the Modules <b>449</b>, <b>450</b> may also be incorporated into the operating system <b>452</b>, the I/O device drivers <b>458</b> or other such logical division of the data processing system <b>405</b>. Thus, the present invention should not be construed as limited to the configuration of <figref idref="DRAWINGS">FIG. 29</figref>, which is intended to encompass any configuration capable of carrying out the operations described herein.
